I agree about taking Deck Devastation Virus out, it's almost unusable in your deck. Taking it out for another Solemn Warning would make this deck perfect. You've done a really good job with this deck!

Edit: Good work on your deck, it's turning out to be quite something. Is it supposed to have only 39 cards in the maindeck though or is that oppression supposed to be in there? Also why are you calling it a synchro deck when it has only has 1 tuner?
